“…Axillary inflorescences produce resupinate flowers, in which the downward labellum is generally united to the column forming a floral tube and a landing platform for pollinators ( Figure 3 a) [ 4 , 44 ]. The flowers exhibit an anther bending downward ( Figure 3 b) [ 44 , 45 ], in which the pollen content is separated from the stigma by the rostellum ( Figure 3 c), a membrane that forms a physical barrier between the female and male reproductive systems, avoiding self-pollination [ 44 , 46 , 47 ]. The rostellum can be absent, as in V. inodora and V. guianensis flowers [ 48 , 49 ].…”

Vanilla is a worldwide cherished condiment, and its volatile market is associated with the so-called “vanilla crisis”. Even though only two species (Vanilla planifolia and V. × tahitensis) are cultivated on a large scale for commercial purposes, the Vanilla genus is comprised of 140 species. The present review article discusses the facets of this crisis, and vanilla crop wild relatives (WRs) are showcased as alternatives to overcome them. Historical, taxonomic, and reproductive biology aspects of the group were covered. Emphasis was given to the metabolic characterization of the vanilla crop WRs, highlighting their main chemical classes and the potential flavor descriptors. Many of these species can produce important flavor compounds such as vanillin, vanillic acid, and acetovanillone, among others. Overall, this review compiles valuable information that can help unravel new chapters of the history of this treasured product by evidencing the biotechnological potential of vanilla crop WRs.

In epiphytes, aerial roots are important to combat water‐deficient, nutrient‐poor, and high‐irradiance microhabitats. However, whether aerial roots can respond to gravity and whether auxin plays a role in regulating aerial root development remain open‐ended questions. Here, we investigated the gravitropic response of the epiphytic orchid Phalaenopsis aphrodite. Our data showed that aerial roots of P. aphrodite failed to respond to gravity, and this was correlated with a lack of starch granules/statolith sedimentation in the roots and the absence of the auxin efflux carrier PIN2 gene. Using an established auxin reporter, we discovered that auxin maximum was absent in the quiescent center of aerial roots of P. aphrodite. Also, gravity failed to trigger auxin redistribution in the root caps. Hence, loss of gravity sensing and gravity‐dependent auxin redistribution may be the genetic factors contributing to aerial root development. Moreover, the architectural and functional innovations that achieve fast gravitropism in the flowering plants appear to be lost in both terrestrial and epiphytic orchids, but are present in the early diverged orchid subfamilies. Taken together, our findings provide physiological and molecular evidence to support the notion that epiphytic orchids lack gravitropism and suggest diverse geotropic responses in the orchid family.
